Airthings Wave Smart Radon Detector

  • Continuous monitoring of radon, temperature and humidity

  • Radon gas fluctuates daily and needs constant monitoring to minimize negative health effects

A Smart Radon Detector For Everyone

Radon gas is a radioactive gas that is found in all buildings at varying levels. It is the leading cause of lung cancer among non-smokers and kills more than six times the amount of people than home fires and carbon monoxide poisoning combined. It is invisible, is found everywhere and fluctuates daily.

Radon is one of the most important components in our indoor air quality. The only way to know if you are exposed to radon is to measure daily

This Is Not Just A Radon Detector

Airthings Wave will provide you with detailed information about radon, temperature and humidity levels right on your phone. View daily, weekly, monthly and yearly measurements in the free mobile app. Use the data to take the necessary steps to protect your home and loved ones from the dangers of radon gas.

The importance of a long battery life, coupled with the requirement for an easy-to-set-up connection, made us go for a low-energy Bluetooth solution. 2 AA batteries will provide you with approximately 1.5 years of peace of mind.

When you are within range of the unit, Wave’s data will constantly update in the app. You will receive notifications when radon levels are high or when the battery levels are low. When radon levels are dangerous you can also receive notifications via email or by using IFTTT. In addition, read data directly from your Airthings Wave over bluetooth using our Python script available at
